If you've seen Stanley Kubrick's film adaptation of Stephen King's The Shining and thought it was solely about one man's descent into madness, guess what? You were wrong.

Opening in limited release Friday, Rodney Ascher's new documentary Room 237 floats the idea that there are a myriad of secrets woven into Kubrick's blood-soaked fright fest.

Some theories posit The Shining is Kubrick's veiled apology for faking the Apollo moon landing, while others say the film is his attempt to deal with the Holocaust and the genocide of the American Indians.

One thing is for certain, there are a lot more puzzling aspects to the film than blood-soaked hallways, a man in a bear suit and Jack Nicholson's 'Heeeere's Johnny!'
